Title: Automated mechanical manual shift transmission
Inventor: SCHMIDT HANS G DIPL ING
IPC: B60W10/10
Filed: 1986-08-14
Abstract: Arrangement of an engine (especially an internal combustion engine in the motor vehicle) with a conventional mechanical manual shift transmission, characterised in that the transmission is shifted automatically by a programmable control. This control (computer) is programmed so that it always selects the most appropriate transmission shift stage at any time, thereby to some extent simulating a conventional automatic transmission. Engine and transmission are equipped with corresponding sensors, in order to detect important characteristic variables. The transmission shifting criteria derived from these are programmed according to the performance characteristics of the engine so that a certain performance (for example lowest possible fuel consumption or greatest possible acceleration), which in turn is automatically adjusted to the respective driving situation. An accelerator pedal determines the acceleration according to which the speed of travel and engine speed are calculated and held constant relative to the fuel. The pedal has a non-linear characteristic curve with brake, constant and acceleration range. The arrangement is equipped so that it is possible to intervene in the control process (for example, in order to change down) or so that it can also be shifted manually in the conventional way in the event of a malfunction. <IMAGE>

Patent DE-3639289-A1 (DE)
Title: Air purification method
Inventor: TISCHENDORF JOACHIM PROF DR IN
IPC: G21F9/02
Filed: 1986-11-17
Abstract: The invention relates to an air purification method which affords especially pure air in a biological sense. It is intended for use in biocleanrooms and other cleanrooms, as well as for comfort purification problems, e.g. breakdowns in nuclear power plants. In addition to the known particulate filters, chemisorption compositions and the like, the purification method utilises a thermal technique which is due to the fact that air is additionally humidified, condensation takes place and the condensed drops are then removed by special eliminator plates. The air to be purified is initially cooled, then subjected to steam humidification in to the fog region and the condensed particles are then removed both on condensation ice surfaces and by plate elimination. At the same time, the Facy effect is utilised during the condensation on ice surfaces.
Patent DE-3639995-A1 (DE)
Title: Stabilising suspension for a vehicle
Inventor: TUCZEK FRANZ DR ING
IPC: B60G17/033
Filed: 1986-11-22
Abstract: In a, for example, four-wheel vehicle with pneumatic or hydropneumatic spring elements, the gas cushions of the spring elements are controlled with the aid of bearing elements and by means of a compressor so that when cornering and when braking or accelerating, gas is transferred from the gas cushions of extended spring elements into the gas cushions of compressed spring elements until the level position of individual spring elements is re-established. In this way, the vehicle is stabilised in the case of dynamic ride movements and the body remains parallel to the road at all times, there being no need for means of static level control, or these being disabled. Non-return valves upstream of the inlet chamber and downstream of the outlet chamber of the compressor prevent any exchange of gas between the gas cushions of simultaneously extended and compressed spring elements.

Title: Covering, in particular for surfaces suitable for foot traffic
Inventor: GOETZ ROBERT
IPC: E01C7/30
Filed: 1987-04-25
Abstract: The invention relates to a covering, in particular for surfaces suitable for foot traffic, which can be installed in a similar manner to, for example, a wear-resistant layer in road building and path building and consists essentially of bound inorganic substances. According to the object of the present invention, a covering is sought which is economical to produce and install, avoids joints, is not hard and neither reflects nor absorbs light. This object is achieved in that an air-drying or self-drying adhesive is used as binder for the solid or granular covering components (3, 5) of the covering (1). Said adhesive is viscous during processing and, mixed with the covering components (3, 5), encapsulates the latter (cf. 8) and, after a drying phase, forms a permanently resilient and elastic, water-resistant and oil-resistant and frostproof binder (4) between the covering components (3, 5). <IMAGE>

Patent DE-3744537-A1 (DE)
Title: Wireless sound transmission by means of light
Inventor: KOCK GERHARD DIPL ING
IPC: H04J3/06
Filed: 1987-12-30
Abstract: The invention relates to the wireless sound transmission for a number of transmitting stations additively to one or more receivers with the aid of light, with particularly low use of energy at the transmitter and, a prerequisite for wireless operation. The object is achieved by the invention in that the positive and negative sound signal components are transmitted separately by each transmitting station on two different channels and by pulse amplitude modulation of light, all transmitting stations jointly additively use these two channels and in that all transmitting stations are synchronised with respect to the pulse transmission times, and after reception, the aggregate sound signal of all transmitting stations is obtained by subtraction of the two channels from one another and subsequent demodulation. Due to this method, all of the transmitting energy can be put into the information-carrying side bands which means a considerable saving in energy. The required peak transmitting amplitude is at least halved compared with the known methods and interference is considerably reduced due to the subtraction.
Patent DE-3802486-A1 (DE)
Title: Device for cleaning mechanical appliances, small parts and/or electronic switching units
Inventor: SCHMITZ RUDOLF
IPC: B08B3/00
Filed: 1988-01-28
Abstract: The invention relates to a device for cleaning mechanical or electrical appliances or devices by means of sprayed-on cleaning liquids and compressed-air jets directed onto them. In order to obtain a mobile device which is independent of special disposal arrangements, the outgoing air, which is sucked off from the cleaning chamber 3 by means of a blower 30 via a first impact filter 13, is conveyed into a compensating chamber 31, from which it can, via further impact filters 33, enter a collecting space 34 which returns a substantial part of the cleaned blower air into the cleaning chamber 3 and which is provided with a draw-off space 36 which is delimited by a shroud 37 and which is followed by an outgoing-air line 40, via which the outgoing air, which has been cleaned by an activated-carbon filter 41, can pass into the room, in which the cleaning device is being operated. By returning a substantial part of the blower air into the cleaning chamber, for example for drying processes, it is only necessary to carry off to the outside relatively small air quantities which occur as leakage air. As a result of the two impact filters, the calming and the activated-carbon filter, a cleaning of the outgoing air is achieved, which is so extensive that it can be blown out harmlessly. <IMAGE>
